All discharges of stormwater, surface water,
groundwater, roof runoff, subsurface drainage or other waters not
intended to be treated in the POTW shall be made to storm sewers or
natural outlets designed for such discharges. Any connection, drain
or arrangement which will permit any such waters to enter any other
wastewater sewer shall be deemed to be a violation of this section
and this chapter.
No person shall contribute or cause to be contributed,
directly or indirectly, any substances or wastewater which will interfere
with the operation or performance of the POTW. These general prohibitions
apply to all such users of a POTW whether or not the user is subject
to National Categorical Pretreatment Standards or any other national,
state or local pretreatment standards or requirements. A user may
not contribute the following substances to any POTW:
A.
Any liquids, solids or gases which by reason of their
nature or quantity are or may be sufficient either alone or by interaction
with other substances to cause fire or explosion or be injurious in
any other way to the POTW or to the operation of the POTW. At no time
shall two successive readings on an explosion hazard meter at the
point of discharge into the POTW (or at any point in the POTW) be
more than 5% nor any single reading over 10% of the lower explosive
limit (LEL) of the meter. Prohibited materials include, but are not
limited to, paints, petroleum products, gasoline, kerosene, naphtha,
benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides,
chlorates, perchlorates, bromates, carbides, hydrides and sulfides
and any other substances which the Town, the state or EPA has notified
the user is a fire hazard or a hazard to the POTW.
B.
Solid or viscous substances which may cause obstruction
to the flow in a sewer or other interference with the operation of
the wastewater treatment facilities, such as but not limited to grease,
garbage with particles greater than 1/2 inch in any dimension, animal
guts or tissues, paunch manure, bones, hair, hides or fleshing, entrails,
whole blood, feathers, ashes, cinders, sand, spent lime, stone or
marble dust, metal, glass, straw, shavings, grass clippings, rags,
spent grains, spent hops, wastepaper, wood, plastics, gas, tar, asphalt
residues, residues from refining or processing of fuel or lubricating
oil, mud or glass grinding or polishing wastes.
C.
Any wastewater which causes corrosive damage or hazard
to structures, equipment or personnel of the POTW, but in no case
discharges having a pH lower than 5.0 or greater than 12.0.
D.
Any wastewater containing toxic pollutants in sufficient
quantity, either singly or by interaction with other pollutants, to
injure or interfere with any wastewater treatment process, constitute
a hazard to humans or animals, create a toxic effect in the receiving
waters of the POTW or to exceed a limitation set forth in a categorical
pretreatment standard. A toxic pollutant shall include but not be
limited to any pollutant identified pursuant to Section 307(a) of
the Act.
E.
Any noxious or malodorous liquids, gases or solids
which, either singly or by interaction with other wastes, are sufficient
to create a public nuisance or hazard to life or are sufficient to
prevent entry into the sewers for maintenance and repair.
F.
Any substance which may cause the POTW's effluent
or any other product of the POTW, such as residues, sludges or scums,
to be unsuitable for reclamation and reuse or to interfere with the
reclamation process. In no case shall a substance discharged to the
POTW cause the POTW to be in noncompliance with sludge use or disposal
criteria, guidelines or regulations developed under Section 405 of
the Act; any criteria, guidelines or regulations affecting sludge
use or disposal developed pursuant to the federal Solid Waste Disposal
Act, the Clean Air Act,[1] the Toxic Substances Control Act,[2] or state criteria applicable to the sludge management
method being used.
G.
Any substance which will cause the POTW to violate
its SPDES permit or the receiving water quality standards.
H.
Any wastewater with objectionable color not removed
in the treatment process, such as, but not limited to, dye wastes
and vegetable tanning solutions.
I.
Any wastewater which contains heat in amounts which
will accelerate the biodegradation of wastes, causing the formation
of excessive amounts of hydrogen sulfide in the POTW or inhibit biological
activity in the POTW treatment plant, but in no case shall the discharge
exceed 65° C. (150° F.) or cause the temperature at the POTW
treatment plant influent to exceed 40° C. (104° F.).
J.
Any pollutants, including oxygen demanding pollutants
(BOD, etc.) released at a flow rate and/or pollutant concentration
which a user knows or has reason to know will cause interference to
the POTW. In no case shall a slug load have a flow rate or contain
concentration or qualities of pollutants that exceed for any time
period longer than 15 minutes more than five times the average twenty-four-hour
concentration, quantities or flow during normal operation, unless
the facilities can accommodate such load and prior approval, in writing,
has been obtained from the Town Engineer.
K.
Any wastewater containing any radioactive wastes or
isotopes of such half-life or concentration as may exceed limits established
in compliance with applicable state or federal regulations.
L.
Any wastewater containing more than 100 milligrams
per liter of oils, fat or grease unless the POTW can accommodate such
discharge and prior approval, in writing, has been obtained from the
Town Engineer.
A.
No person shall discharge or cause to be discharged
to any POTW, wastewaters containing substances subject to an applicable
federal categorical pretreatment standard promulgated by EPA in excess
of the quantity prescribed in such applicable pretreatment standards
except as otherwise provided in this section.
B.
Upon application by a Class III user, the Town in
conjunction with the BSA may revise any limitations on substances
specified in the applicable pretreatment standards to reflect removal
of the substances by the POTW treatment plant. The revised discharge
limit for specified substances shall be derived in accordance with
federal law.
C.
Upon application by a Class III user, the Town in
conjunction with the BSA may adjust any limitation on substances specified
in the applicable pretreatment standards to consider factors relating
to such person which are fundamentally different from the factors
considered by EPA during the development of the pretreatment standard.
Requests for and determinations of a fundamentally different adjustment
shall be in accordance with federal law.
D.
The Town Engineer shall notify any Class III user
affected by the provisions of this section and establish an enforceable
compliance schedule for each.
Nothing in this article shall be construed as
preventing any special agreement or arrangements between the Town
and any user of the POTW whereby wastewater of unusual strength or
character is accepted into the system and specially treated subject
to any payments or user charges as may be applicable. Federal categorical
pretreatment standards shall not be waived.
The conservation of water and energy shall be
encouraged by the Town Engineer. In establishing discharge restrictions
upon industrial users, he shall take into account already implemented
or planned conservation steps revealed by the Class III user. Upon
request of the Town Engineer, each industrial user shall provide the
Town Engineer with pertinent information showing that the quantities
of substances or pollutants have not been nor will be increased as
a result of the conservation steps. Upon such a showing to the satisfaction
of the Town Engineer, he may make adjustments to discharge restrictions,
which have been based on concentrations, to reflect the conservation
steps.

B.
For facilities with multiple outfalls to the public
sewer, the limits established above shall apply to each individual
outfall. The exceptions to this are mass limits and total phenol.
Mass discharge limits issued to any facility under the SPDES permit
system shall apply to the total discharge from all outfalls at that
facility. The phenol limit shall also apply to the composite of all
discharges from a facility.
State and Buffalo Sewer Authority requirements
and limitations on discharges shall apply in any case where they are
more stringent than federal requirements and limitations and those
in this chapter. In all cases, the most stringent limit, federal,
state, BSA or local shall apply.
The Town reserves the right to establish by
law more stringent limitations or requirements on discharges to the
POTW if deemed necessary to comply with the objectives presented in
this article.
No user shall ever increase the use of process water or, in any way, attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in the federal categorical pretreatment standards or in any other pollutant-specific limitation developed by the Town, state or BSA. Dilution may be an acceptable means of complying with some of the prohibitions set forth in § 198-32C of this article upon prior approval in writing by the Town Engineer.
A.
Each user shall provide protection from accidental
discharge of prohibited materials or other substances regulated by
this chapter. Facilities to prevent accidental discharge of prohibited
materials shall be provided and maintained at the owner or user's
own cost and expense.
B.
In the case of an accidental discharge, it is the
responsibility of the user to immediately telephone and notify the
POTW of the incident. The notification shall include location of discharge,
type of waste, concentration and volume and corrective actions.
C.
A notice shall be permanently posted on the user's
bulletin board or other prominent place advising employees whom to
call in the event of a dangerous discharge. Employers shall ensure
that all employees who may cause or suffer such a dangerous discharge
to occur are advised of the emergency notification procedure.
D.
Within five days following an accidental discharge,
the user shall submit to the Town Engineer a detailed written report
describing the cause of the discharge and the measures to be taken
by the user to prevent similar future occurrences. Such notification
shall not relieve the user of any expense, loss, damage or other liability
which may be incurred as a result of damage to the POTW, fish kills
or any other damage to person or property; nor shall such notification
relieve the user of any fines, civil penalties or other liability
which may be imposed by this chapter or other applicable law.
A.
Measurements, tests and analyses of the characteristics
of wastewater to which reference is made in this chapter shall be
determined in accordance with procedures established by the Town Engineer
pursuant to Standard Methods and also to Section 304(g) of Act and
contained in 40 CFR, Part 136, and amendments thereto, or with any
other test procedures approved by the Town Engineer and which comply
with state and federal law.
B.
Measurements, tests and analyses of the characteristics
of wastewater required by this chapter shall be performed in a qualified
laboratory.
If the drainage or discharge from any establishment
causes a deposit, obstruction or damage to the POTW, the Town Engineer
shall cause the deposit or obstruction to be promptly removed or cause
the damage to be promptly repaired. The cost for such work, including
materials, labor and supervision, shall be borne by the person causing
such deposit, obstruction or damage.
